Hardenable putty and production method thereof

Abstract

According to one aspect of the present invention, a hardenable putty used for impression taking includes an inorganic filler at 60% by mass or greater and 85% by mass or less, wherein consistency of the hardenable putty is greater than or equal to 35, and wherein a median diameter of the inorganic filler is greater than or equal to 5 μm and less than or equal to 50 μm on a weight basis.

1 . A hardenable putty used for impression taking, the hardenable putty comprising:
 an inorganic filler at 60% by mass or greater and 85% by mass or less,   wherein consistency of the hardenable putty is greater than or equal to 35, and   wherein a median diameter of the inorganic filler is greater than or equal to 5 μm and less than or equal to 50 μm on a weight basis.   
     
     
         2 . The hardenable putty according to  claim 1 , further comprising:
 an organopolysiloxane including two or more alkenyl groups;   an organohydrogenpolysiloxane including two or more constituent units represented by a general formula HSiR 2 O 1/2  (where R represents a substituted or unsubstituted hydrocarbon group having 1 to 10 carbon atoms in the formula);   a platinum-based catalyst; and   a release agent.   
     
     
         3 . A method for producing the hardenable putty according to  claim 2 , the method comprising:
 mixing a first paste that includes the organopolysiloxane and the platinum-based catalyst and that does not include the organohydrogenpolysiloxane with a second paste that includes the organopolysiloxane and the organohydrogenpolysiloxane and that does not include the platinum-based catalyst.
